HAYS'IACKER.

Application filed January 30, 1922. Serial No. 532,779.

To all whom it may concern:

Be it known that I, FRANK BLAINE GoA'rns, a citizen of the United States, residing at J ohnstown, in the county of Weld and State of Colorado, have invented certain new and useful Improvements in Haystackers, of, which the following is a specification.

My invention relates to an improvement in haystackers.

One of the essential features of this invention is an arrangement by which a pair of sliding arms carrying a hay-rack can be riased and extended from the low position where the stack is commenced to the high position at which the stack is topped off, delivering the hay over toward the center of the stack.

One important object of this invention is to make provision for building' a higher and better stack than is possible with other machines.

Among other features this invention consists in pivotally mounted extensible arms carrying a rack with springs so located and arranged as to allow the stacker when it is delivering the hay on the stack to swing over and deliver the load toward the center of the stack, these springs also having the function of bracing the stacker-arms against wind when in operation.

This invention also makes provision for buildinga large stack, and one which can be topped up to a sharp point, so as to shed the rain and prevent the hay in the stack from being spoiled.

Another feature is the part played by the springs which are so located and arranged that they start the rack on the return movement after delivering its load upon the stack.

In the accompanying drawings Fig. 1 is a side view;

Fig. 2 is a longitudinal sectional view;

Fig. 3 is a plan;

Figs. 4 and 5 are views taken at rightangles to each other, that is to say, side and rear views respectively, of the stacker in its elevated position.

The invention consists of a frame 1, composed of main sills A, a post 2, and crosssills 3. Braces 4: are adapted to rest upon the main sills A and constitute a rigid support for the superstructure of the stacker.

Extensible arms 5 are pivotally connected by bolts 6 to these braces, and the outer sliding sections 6 of these arms carry the rack 7 which receives the hay at the level of the ground and hoists up over the stack when raised, as shown in Figs. 4 and 5. These sliding sections of the arms are slidably connected with the arms 5 by guides 8.

An A-shaped boom 9 is pivotally mounted on the main sills, and laterally supported and confined therebetween by the crossrod 10.

A V-shaped truss-rod 11 extends from the boom 9 with which it is pivotally connected, preferably through the stirrup 12, to the forward end of the arms 5.

Bars 18 are pivotally connected at their upper ends by bolts 14 or other means to the upper ends of the swinging arms 15, which latter are pivoted by means of bolts 16 to the sills A.

Inverted U-shaped tensionlinks 17 are pivotally connected with the sills, and are loosely and slidably connected with the bars 13 by the springs 18. The free ends of the bars 13 normally rest by gravity upon the sliding sections 6, and, as the latter are raised, slide ouwtardly thereupon engaging pins 25 in the holes 26 formed in the inner ends of the extension sections 6 of the arms as shown in the drawings, thereby extending'the rack as the arms are raised toward and to a perpendicular position, and, after reaching a certain height, the springs and U-shaped links apply tension to the bars, thereby steadying and supporting the arms against the pressure of the wind when the stacker is in operation, and also having the effect of pulling the rack past the dead center in order that it may travel back to the ground by gravity when it is lowered to receive another load of hay.

The rack is raised through the medium of a cable 19, which cable is rove around sheaves 20, 21, 22 and 23.

After the rack 7 has been loaded with hay, power is applied to the cable 19, starting the rack and its load on their upward journey. As the arms are raised the bars 13 come in contact with the pins 25 thus forcing the sliding sections 6 outward as the rack travels upward. After the rack and arms have passed the dead center, the load falls from the rack onto the stack by gravity. The rack is drawn down to its normal position by means of the U-shaped tension-links 17 and the springs 18 as herebefore described.

In this way, a stacker is provided of a type which will go over and deliver the hay upon the top of the large, high stack, making it possible to build a stack, and thus by delivering the hay directly upon the top of the stack making it possible for the operator to complete his stack so he can top it up with a sharp point which will shed the rain and prevent the hay in the stack from being spoiled by the rain. The springs force the rack back to the starting position, and form a lateral brace for the arms.

I claim: I

1. In a haystacker, the combination with a frame, extensible arms pivoted thereto and carrying a rack, and swinging arms pivoted to the frame, of bars pivoted to the swinging arms, means mounted on the extensible arms for engagement with the bars whereby the arms may be lengthened, tension-links pivoted to the frame, and springs extending from the bars to the tension-links forcreating tension upon the bars when the arms are in an elevated position.

2. In a haystacker, the combination with a frame, extensible arms pivoted thereto and carrying a 'ack, and swinging arms pivoted to the frame, of bars pivoted to the swinging arms, means mounted on the extensible arms for engagement with the bars whereby the arms may be lengthened, tension-links pivoted to the frame, springs extending from the bars to the tension-links for creating tension upon the bars when the arms are in an elevated position, and a cable for raising and lowering the extensible arms and rack.

3. In a haystacker, the combination with a frame, extensible arms pivoted thereto and carrying a rack, and swinging arms pivoted to the frame, of bars pivoted to the swinging arms, means mounted on the extensible arms for engagement with the bars whereby the arms may be lengthened, tension-links pivoted to the frame, springs extending from the bars to the tension-links for creating tension upon the bars when the arms are in an elevated positlon, an A-shaped boom and a V-shaped truss-rod connected together and pivotally connected respectively with the main frame and the extensible arms, and a cable rove around sheaves carried by the boom and frame for raising and lowering the extensible arms and rack.

i. The combination with a frame, extensible arms pivoted to. the frame and carrying a rack, a boom pivoted to the frame, a trussrod pivoted to the extensible arms and connected with the boom, a sheave mounted approximately at the point of intersection of the boom and truss-rod, bars pivotally mounted on the frame for engagement with the extensible arms, links pivoted to the frame, springs connecting said links with the bars for applying tension thereto when said bars are in a raised position, and a cable secured to the boom and passed around the several sheaves for raising and lowering the rack.

5. The combination with a frame, extensible arms pivoted thereto, means for raising and lowering said arms, bars pivotally connected with the frame and adapted to engage said extensible arms, links pivotally connected with the frame, and springs, connected with the links at one end and withthe bars at their other end.

6. The combination with a frame, extensible arms pivoted thereto, means for raising and lowering said arms, bars pivotally connected with the frame and adapted to engage said extensible arms, links pivotally connected with the frame, springs. connected with the links at one end and with thebars at their other end, a boom mounted onthe frame and connected with the arms, and a cable connected with the boom for raising and lowering the arms,

In testimony whereof I ailix my signature.
